Question

Which of following organometallic compound is and $\pi$ bonded?

• A. $\left[Fe{(}^5{C}_5{H}_5{)}_2\right]$
• B. $K\left[PtC{l}_3{(}^{2}C2H_4\right)]$
• C. $\left[Co\right(CO{)}_{5}N{H}_3{]}^{+2}$
• D. $Fe(C{H}_3{)}_3$

Answer 1

Answer: (C)

$\left[Co\right(CO{)}_{5}N{H}_3{]}^{+2}$

In Metal carbonyls, there are $2\pi$ bonds present between metal and carbon. So $\left[Co\right(CO{)}_{5}N{H}_3{]}^{+2}$ is $\pi$ bonded.
